Special Features :

　　• Welded diaphragm 　　• Wide range of diaphragm material 　　• Most suitable for slurry & corrosive service 　　• Flushing Ring, Flange & Diaphragm are available in various type of SS & Exotic materials.

Applications :

Diaphragm seals are provided in the instruments like pressure gauges, switches, transmitters in order to isolate the sensing element from the main service due to its corrosive, viscous and sedimented nature and to avoid clogging and solidifi cation. These kind of seals are widely used in the viscous & corrosive services where fl ushing is required periodically & frequently.
